Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454250, here are decompositions:

29 + 31454221 = 31454250
31 + 31454219 = 31454250
53 + 31454197 = 31454250
59 + 31454191 = 31454250
89 + 31454161 = 31454250
101 + 31454149 = 31454250
103 + 31454147 = 31454250
127 + 31454123 = 31454250

Showing the first eight; more decompositions exist.
